|Sultan of Rum|
|Successor||Kilij Arslan I|
|Issue||Kilij Arslan I|
Suleiman ibn Qutalmish (Turkish: Kutalmo?lu Süleyman ?ah, Old Anatolian Turkish? , Persian: ) founded an independent Seljuk Turkish state in Anatolia and ruled as Seljuk Sultan of Rûm from 1077 until his death in 1086.
Suleiman was the son of Qutalmish, who had struggled unsuccessfully against his cousin Alp Arslan for the throne of the Great Seljuk Empire. When Kutalmish died in 1064, Suleiman fled with his three brothers into the Taurus Mountains and there sought refuge with Turkmen tribes living beyond the borders of the empire. Alp Arslan responded by launching a series of punitive expeditions against them. Of the four brothers, Suleiman alone survived the raids and was able to consolidate his leadership of the Turkmen.
In 1078, the Byzantine emperor Michael VII sought the help of Suleiman against Nicephorus Botaneiates, the commander of the Anatolic Theme, who had challenged the emperor for the throne. Suleiman intercepted Botaneiates' small force between Cotyaeum and Nicaea, whereupon the usurper persuaded Suleiman to join his rebellion by offering him incentives superior to those of the emperor. Nicephorus' bid for power was successful, and in return for their support Suleiman's Turkmen were allowed to settle on the Asiatic side of the Bosphorus, near Constantinople itself. Two years later, Suleiman lent his support to another pretender, Nicephorus Melissenus. It was the latter Nicephorus who opened the gates of Nicaea to the Turkmen, allowing Suleiman to establish a permanent base. All Bithynia was soon under Suleiman's control, a circumstance which allowed him to restrict communication between Constantinople and the former Byzantine subjects in Anatolia.
In 1084, Suleiman left Nicaea, leaving his kinsman Abu'l Qasim in charge.
Suleiman expanded his realm. In 1084, Antioch was ruled by Philaretos Brachamios, a Byzantine general and warlord of Armenian heritage, who was known for his greed and oppression towards his folk and soldiers. He even had his own son Barsama imprisoned for over a disagreement. When Philaretos left for ?anl?urfa (Edessa), a military governor named ?smail (thought to be Turkish) freed Barsama and together they offered Antioch to Suleiman. Suleiman left his kinsman Abu'l Qasim in charge of Nicaea and came to Antioch with 300 men. His trip lasted 12 days, during which the beg of Mengüjek joined him with mounted troops. Thus, with the collaboration of Philaretos' son and ?smal, he captured the city on 12 December 1084 and the castle in 12 December 1085. Without touching its inhabitants Suleiman gave quarter and unconditionally released his prisoners. He also issued an ordinance to be kind to the Christian folk, not to take anything from them nor enter their houses and not to marry their daughters. Moreover, when Suleiman-Shah converted the church of St. Cassianus to a mosque, instead of taking all of the gained treasures, he ordered them to be sold in the city for low prices. Later, upon the request of the Christian citizens, he allowed the St. George and Meryemana churches to be built. 
In 1086, Suleiman, seeking to expand his dominion, placed Aleppo under siege and demanded its surrender. The emir of Aleppo sent a message to Tutush I, the Seljuk ruler of Syria, stating he would hand the city over to him. Suleiman, hearing of the approach of Tutush's forces, raised the siege and marched to meet him. Near Aleppo, Suleiman's forces fled before Tutush's army, while Suleiman was killed. Suleiman's son, Kilij Arslan I, was captured, and Malik Shah transferred him to Isfahan as a hostage.
Upon the death of Malik-Shah I, Kilij Arslan I re-established the Sultanate of Rûm.
